It is not safe to rely on the system’s timezone settings

Posted by on January 31, 2011 No comments

Recently I have been having the following error on my PHP code every time I call the PHP function date();  Mostly when running it on my local test server.

Warning: date(): It is not safe to rely on the system’s timezone settings

Cause: Since PHP5.1.0 the E_RESTRICT setting causes PHP to report error for every call
to a date/time function, if no default time is set.

Fix: There are 2 approaches to  resolving this.

  1. Set time setting to your PHP script with the function date_default_timezone_set();  with the intended time zone/location eg: for GMT one can use date_default_timezone_set(‘Europe/London’);
  2. Set time setting to your php.ini file by editing the line ;date.timezone = to date.timezone = “Europe/London” or you required location. This is good for setting a server wide time setting.

Automatically display form data with PHP

Posted by on May 13, 2009 No comments

This is a simple PHP  script to automatically display (dump output)  data submited from a html form.

The form setup

  • all inputs (form fields) need to have the same name with [] at the end to turn it into an array,  e.g <input type=text name=formdata[]>

formq.html content

<form method=post action=showme.php>
Name: <input type=text name=formdata[]><br>
Email: <input type=text name=formdata[]><br>

<input type=submit value=ok>
</form>

The Script setup

showme.php content

<?php
$data = $_POST['formdata']; # get value from the form fields

foreach ( $data as $key => $value ) { # loop through array collecting the results

echo  “$value<br>”;  # output the data  – print to page
}
?>
